PROF. HENDERSON TO LECTURE AT SORBONNE

Lawrence J. Henderson, '98, Professor of Biological Chemistry, has been appointed Exchange Professor to France by the Corporation of the University, to take the place of Professor Albert Bushnell Hart '80, who has found it impossible to make the trip to Europe this winter.

Professor Henderson will lecture at the Sorbonne during the second half of the present academic year, while Dean Henri Guy of the University of Toulouse is at the University giving a course on the history of the Sonnet in France and a series of public lectures on Corneille. Dean Guy arrived in Cambridge last Wednesday.

As Professor Henderson is already at Grenoble, France, on leave of absence from the University and engaged in research, he will be able to assume his duties in Paris without loss of time. Meanwhile Professor Hart, the historian, who was to have been sent to France in exchange for Dean Guy, will be on sabbatical leave of absence from the University.

Researches Noteworthy

Lawrence J. Henderson is one of the most distinguished members of the University teaching staff, and his researches in the application of chemistry to biology and medicine have attracted wide-spread attention among students of these subjects. He was born in 1878, was graduated from Harvard College in 1898 and from the Medical School in 1902, spent two years doing post-graduate work at the University of Strasbourg and since then has taught at the University.

During the war, on behalf of the Medical Department of the Army, he studied the physical chemistry of bread and bread-making, being assisted in this work by a number of officers. Since the war he has been engaged in various chemical studies of blood and of hemoglobin. He has made some valuable discoveries about the constancy of the alkalinity of the blood, and more recently about the mechanism by which the red corpuscles in the blood take in and give out oxygen.

During the present year Professor Henderson has been on leave of absence for research in Europe.
